CVE-2023-31317
HighSummary
Improper restriction of operations within the bounds of a memory buffer in the AMD secure processor (ASP) could allow an attacker to read or write to protected memory potentially resulting in arbitrary code execution.
Risk Assessment
The organization may be exposed to unauthorized access to protected data and the potential execution of malicious code, leading to serious security breaches.
Recommendation
It is recommended to update the software and monitor systems for potential attempts to exploit this vulnerability.
Other vulnerabilities in AMD secure processor (ASP)
See all- CVE-2023-31316High
Improperly preserved integrity of hardware configuration state during a power save/restore operation in the AMD Secure Processor (ASP) could allow an attacker with the ability to write outside the trusted memory range (TMR) to change the execution flow of the Video Core Next (VCN) firmware.
- CVE-2025-61972High
The lack of lock bit protection for NBIO registers may allow a local admin-privileged attacker to gain arbitrary access to the System Management Network (SMN), potentially leading to arbitrary code execution in the AMD Secure Processor (ASP) and loss of confidentiality and integrity for SEV-SNP guests.
- CVE-2023-20572Medium
An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing the input of an arbitrary message, potentially leading to a loss of data integrity.
- CVE-2023-20540Low
An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing arbitrary message input, potentially leading to a loss of data integrity.
